Michael Paquier f1516ad7b3 pgbench: Simplify some port, host, user and dbname assignments
Using pgbench in an environment with both PGPORT and PGUSER set would
have caused the generation of a debug log with an incorrect database
name due to an oversight in 412893b.  Not specifying user, port and/or
database using the option switches, without their respective environment
variables, generated a log entry with empty strings, which was
rather useless.

This commit fixes this set of issues by simplifying the logic grabbing
the connection information, removing a set of getenv() calls that
emulated what libpq already does.  The faulty debug log now directly
uses the information from the libpq connection, and it gets generated
after the connection to the backend is completed, not before it (in the
event of a failure libpq would complain with more information about the
connection attempt so the log is not really useful before anyway).

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

	https://www.postgresql.org/download/

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software may be obtained at
https://www.postgresql.org/download/.  For more information look at our
web site located at https://www.postgresql.org/.
